No Film At 11: the Case For the Less-Video-Is-More MOOC 1

Posted by Soulskill
from the better-learning-through-animated-GIFs dept.
theodp writes: In Why My MOOC is Not Built on Video, GWU's Lorena Barba explains why the Practical Numerical Methods with Python course she and colleagues put together has but one video: "Why didn't we have more video? The short answer is budget and time: making good-quality videos is expensive & making simple yet effective educational videos is time consuming, if not necessarily costly. #NumericalMOOC was created on-the-fly, with little budget. But here's my point: expensive, high-production-value videos are not necessary to achieve a quality learning experience." When the cost of producing an MOOC can exceed $100,000 per course, Barba suggests educators pay heed to Donald Bligh's 1971 observation that "dazzling presentations do not necessarily result in learning." So what would Barba do? "We designed the central learning experience [of #NumericalMOOC] around a set of IPython Notebooks," she explains, "and meaningful yet achievable mini-projects for students. I guarantee learning results to any student that fully engages with these!"

Microsoft Rolls Out Project Spartan With New Windows 10 Build 30

from the this!-is!-spar!-tan! dept.
An anonymous reader writes: Today Microsoft released a new Technical Preview build for Windows 10. Its most notable addition is Microsoft's new browser: Project Spartan. In a brief post explaining the basics of the browser, the company says it includes their personal assistant software, Cortana, as well as "inking" support, which lets you write or type on the webpage you're viewing. But the biggest change, of course is the new rendering engine. The "suggestion box" page for Project Spartan is already filling up with idea from users, including one for Trident/EdgeHTML to be released as open source.

Why You Should Choose Boring Technology 76

Posted by Soulskill
from the predictable-headaches dept.
An anonymous reader writes Dan McKinley, a long-time Etsy engineer who now works at online payment processor Stripe, argues that the boring technology option is usually your best choice for a new project. He says, "Let's say every company gets about three innovation tokens. You can spend these however you want, but the supply is fixed for a long while. You might get a few more after you achieve a certain level of stability and maturity, but the general tendency is to overestimate the contents of your wallet. Clearly this model is approximate, but I think it helps. If you choose to write your website in NodeJS, you just spent one of your innovation tokens. If you choose to use MongoDB, you just spent one of your innovation tokens. If you choose to use service discovery tech that's existed for a year or less, you just spent one of your innovation tokens. If you choose to write your own database, oh god, you're in trouble. ... The nice thing about boringness (so constrained) is that the capabilities of these things are well understood. But more importantly, their failure modes are well understood."

IT Jobs With the Best (and Worst) ROI 80

Posted by Soulskill
from the becoming-borg-is-at-both-the-top-and-the-bottom dept.
Nerval's Lobster writes: Over at Dice, there's a breakdown of which tech jobs have the greatest return on investment, with regard to high starting salaries and growth potential relative to how much you need to spend on degrees and certifications. Which jobs top this particular calculation? No shockers here: DBAs, software engineers, programmers, and Web developers all head up the list, with salaries that tick into six-figure territory. How about those with the worst ROI? Graphic designers, sysadmins, tech support, and software QA testers often present a less-than-great combination of relatively little money and room for advancement, even if you possess a four-year degree or higher, unless you're one of the lucky few.

Amazon Launches 'Home Services' For Repair, Installation, and Other Work 78

Posted by Soulskill
from the remember-when-they-sold-books dept.
An anonymous reader writes: Amazon has quietly rolled out a new business called "Home Services," which aims to be a middleman between customers and all sorts of contracted services. It includes things like appliance repair, home cleaning, installation/assembly of products in your car or home, tutoring (academic and musical), and even performance art. Amazon makes money on this by taking a cut of the total price — between 10 and 20 percent. Since everything is geolocated, they have many more options available in big cities than in small rural communities. One of Amazon's goals is to help standardize the price for various services, so there aren't any surprises when the bill comes due.

Poverty May Affect the Growth of Children's Brains 188

Posted by Soulskill
from the money-is-the-root-of-all dept.
sciencehabit writes: Stark and rising inequality plagues many countries, including the United States, and politicians, economists, and — fortunately — scientists, are debating its causes and solutions. But inequality's effects may go beyond simple access to opportunity: a new study finds that family differences in income and education are directly correlated with brain size in developing children and adolescents. The findings could have important policy implications and provide new arguments for early antipoverty interventions, researchers say.

Oops: World Leaders' Personal Data Mistakenly Released By Autofill Error 104

Posted by samzenpus
from the sounds-like-a-case-of-the-mondays dept.
mpicpp writes in with this story about a mistake that saw personal details of world leaders accidentally disclosed by the Australian immigration department. "With a single key stroke, the personal information of President Obama and 30 other world leaders was mistakenly released by an official with Australia's immigration office. Passport numbers, dates of birth, and other personal information of the heads of state attending a G-20 summit in Brisbane, Australia, were inadvertently emailed to one of the organizers of January's Asian Cup football tournament, according to The Guardian. The U.K. newspaper obtained the information as a result of an Australia Freedom of Information request. Aside from President Obama, leaders whose data were released include Russian President Vladimir Putin, German Chancellor Angela Merkel, Chinese President Xi Jinping and British Prime Minister David Cameron. The sender forgot to check the auto-fill function in the email 'To' field in Microsoft Outlook before hitting send, the BBC reports."

Hand-Drawn and Inkjet Printed Circuits for the Masses (Video) 27

Posted by Roblimo
from the give-your-kids-paper-plates-with-lights-that-tell-them-to-eat-their-veggies dept.
We started looking at ways to make instant hand-drawn or inkjet-printed circuit boards because Timothy met an engaging young man named Yuki Nishida at SXSW. Yuki is a co-founder of AgIC, a company that makes conductive ink pens and supplies special paper you can use to write or draw circuits or, if you have the right model of Brother printer, to print them with special inkjet inks. The AgIC people are agressvively putting the 'A' in STEAM by marketing their products to artists and craftspeople. Indeed the second line on their website's home page says, 'AgIC offers handy tools to light up your own art works.' This is an excellent niche, and now that AgIC has developed a circuit eraser (due to ship this April), it may lead to all kinds of creative designs. And as is typical with this kind of company these days, AgIC has been (at least partly) crowdfunded.

A little cursory Google searching will soon lead you to other companies selling into the home/prototype circuit board market, including Cartesian Co and their Argentum 3-D printer that does prototype and short-run PCBs and only costs $899 (on special at the time this was written) and Electroninks, which markets the Circuit Scribe pen and associated materials with an emphasis on education. There are others in this growing field, and a year from now there will probably be more of them, all working to replace the venerable breadboard the same way electronic calculators replaced slide rules.

Silk Road Investigators Charged With Stealing Bitcoin 101

Posted by samzenpus
from the was-that-wrong? dept.
itwbennett writes Two former U.S. government agents face charges related to stealing hundreds of thousands of dollars worth of bitcoin while assisting with an investigation of the Silk Road underground online marketplace, with one accused of using a fake online persona to extort money from operators of the site. Facing charges of wire fraud and money laundering are Carl Force, 46, of Baltimore, a former special agent with the U.S. Drug Enforcement Agency, and Shaun Bridges, 32, of Laurel, Maryland, a former special agent with the U.S. Secret Service. Both served on the Baltimore Silk Road Task Force, which investigated illegal activity on the Silk Road website, the Department of Justice said Monday in a press release.

Robots4Us: DARPA's Response To Mounting Robophobia 83

Posted by samzenpus
from the hug-your-robot dept.
malachiorion writes DARPA knows that people are afraid of robots. Even Steve Wozniak has joined the growing chorus of household names (Musk, Hawking, Gates) who are terrified of bots and AI. And the agency's response--a video contest for kids--is equal parts silly and insightful. It's called Robots4Us, and it asks high schoolers to describe their hopes for a robot-assisted future. Five winners will be flown to the DARPA Robotics Competition Finals this June, where they'll participate in a day-after discussion with experts in the field. But this isn't quite as useless as it sounds. As DRC program manager Gill Pratt points out, it's kids who will be impacted by the major changes to come, moreso than people his age.

China's Foreign Ministry: China Did Not Attack Github, We Are the Major Victims 115

Posted by samzenpus
from the it-wasn't-us dept.
An anonymous reader writes At the Regular Press Conference on March 30, China's Foreign Ministry Spokesperson Hua Chunying responded on the charge of DDoS attack over Github. She said: "It is quite odd that every time a website in the US or any other country is under attack, there will be speculation that Chinese hackers are behind it. I'd like to remind you that China is one of the major victims of cyber attacks. We have been underlining that China hopes to work with the international community to speed up the making of international rules and jointly keep the cyber space peaceful, secure, open and cooperative. It is hoped that all parties can work in concert to address hacker attacks in a positive and constructive manner."

Book Review: Future Crimes 23

from the read-all-about-it dept.
benrothke writes Technology is neutral and amoral. It's the implementers and users who define its use. In Future Crimes: Everything Is Connected, Everyone Is Vulnerable and What We Can Do About It, author Marc Goodman spends nearly 400 pages describing the dark side of technology, and those who use it for nefarious purposes. He provides a fascinating overview of how every major technology can be used to benefit society, and how it can also be exploited by those on the other side. Keep reading for the rest of Ben's review.

Sign Up At irs.gov Before Crooks Do It For You 268

Posted by samzenpus
from the real-you dept.
tsu doh nimh writes If you're an American and haven't yet created an account at irs.gov, you may want to take care of that before tax fraudsters create an account in your name and steal your personal and tax data in the process. Brian Krebs shows how easy it is for scammers to register an account in your name and view your current and past W2s and tax filings with the IRS, and tells the story of a New York man who — after receiving notice from the agency that someone had filed a phony return in his name — tried to get a copy of his transcript and found someone had already registered his SSN to an email address that wasn't his. Apparently, having a credit freeze prevents thieves from doing this, because the IRS relies on easily-guessed knowledge-based authentication questions from Equifax.

Apple Extends Its Trade-In Program 48

from the how-much-will-you-give-me-for-it? dept.
Mark Wilson writes "Earlier in the month it was reveal that Apple was about to start offering gift cards as part of a trade-in program for people buying new a new iPhone. The updated program has now gone live so you can take your old Apple device, or non-Apple smartphone to an Apple store, or mail it in to receive credit. The credit can be used in store or online against the purchase of a new Apple device, and this program expansion is the latest move from Apple to try to tempt users away from other platforms. You can check online to see how much you can expect to receive for your existing phone and decide whether it's worth your while. Hint: it might not be.

How Malvertising Abuses Real-Time Bidding On Ad Networks 99

Posted by samzenpus
from the rotten-apples dept.
msm1267 writes Dark corners of the Internet harbor trouble. They're supposed to. But what about when Yahoo, CNN.com, TMZ and other busy destination sites heave disaster upon visitors? That's the challenge posed by malvertising, the latest hacker Golden Goose used in cybercrime operations and even in some targeted attacks. Hackers are thriving in this arena because they have found an unwittingly complicit partner in the sundry ad networks to move malicious ads through legitimate processes. Adding gasoline to the raging fire is the abuse of real-time ad bidding, a revolution in the way online ads are sold. RTB enables better ad targeting for advertisers and less unsold inventory for publishers. Hackers can also hitch a ride with RTB and target malicious ads on any site they wish, much the way a legitimate advertiser would use the same system.
